I have upgraded the Left4Dead servers to their full versions today. Last night there was crash issues with the dedicated server across the board so I could not upgrade them to full versions.
However they are fully upgraded and running.
Outbreak is an advanced coop server now. (If you think this is too easy (or too hard) then vote to change it) It will cycle through the four campaigns, if you don't want to do the campaign it is currently on, then start a vote to change it to whichever one you want to do. If your the first one on you basically get your pick of the campaign without having to get someone else to approve it.
Infection is now a verses server. The only noticeable complication with this is it sends you right into the game on a random team, you don't get to pick which team your on. However just press your team select button (m by default) if you get sent to a team you don't want to be on (assuming there is slots on the other team).
All this information as well as how to join the servers is listed at

In other news, the TSRP server has been upgraded to 30 slots. We are running 30 slots in a trial period for one to two weeks. We don't expect lag issues, the server box has plenty of resources at the moment (even with the two new l4d servers). What we are evaluating is if admins get overwhelmed or, if there is too many players that it causes confusion in the middle of roleplay, and other similar things.
If you have any questions or comments about the l4d servers, or the TSRP server upgrade, then please let me know. Feedback on how the TSRP Server is doing when it fills up to 30 players would be greatly appreciated.
